Lift Kit for Tandem Axle Fifth Wheel Trailer When Towing with New Truck that Sits Up Taller

Question:

Hi, I have a 2013 heartland torque fifth wheel. I am looking at a new truck that factory sits higher than my current truck. With my current truck I already adjusted the height of the pin box and it is already too close to the bed sides. Unfortunately the axles are already under the springs, so the axle flip kit won’t work. The one thing I did notice is that the springs are almost flat with the weight of the trailer. Are there different springs that could provide some lift? They are 7000# round axles. Any other suggestions on how to make this work? Thank you in advance!

The tandem axle lift kit part # RR23QX that you referenced would be the easiest and best solution to gain 2 inches of height on your trailer suspension. Going with a new 7k leaf spring might help little bit like with the part # e64SR but this is a 6 leaf spring like you have already and is shorter at 24-7/8 inches so you'd most likely have to move hangers around and wouldn't gain a significant amount of height if anything at all.
